AI's New Bottleneck: Why Memory, Not Compute, Is Now the Real Cost Killer
AI got cheaper to compute — and far more expensive to remember.
What is this trend?
Inference economics are now dominated by memory capacity and bandwidth, as KV caches and long contexts constrain throughput, latency, and scale.
- Compute is less often the limiter; moving tokens in and out of memory is.
- KV cache growth drives cost, concurrency limits, and latency in always-on AI.
- Model teams are shrinking memory footprints with smarter attention and compression.
- Systems teams are redesigning storage, packaging, and memory tiers for higher bandwidth.
- The winners will be workloads and platforms that optimize tokens per byte, not just FLOPS.
